Solar hybrid inverters are essential components in modern solar energy systems, offering the flexibility and efficiency needed for optimal energy management. In this blog post, we will delve into the technical aspects of the working mode of solar hybrid inverters, explaining how they integrate various power sources to ensure a seamless energy supply.
Solar Hybrid Inverter Working Mode Explained
The working mode of a solar hybrid inverter can be understood through its ability to manage multiple energy sources simultaneously. Here’s a breakdown of how these inverters operate:
1. PV photovoltaic panel charges the battery
When there is sunlight during the day and the battery is not full, the PV panel charges the battery through MPPT.
2. Grid-connected power generation by PV panels
When there is sunlight during the day and the battery is full, the PV panels are connected to the grid through MPPT, DCAC inverter and enter the power generation mode.
3. Battery Grid Connected Power Generation
There is no sunlight at night, the power stored in the battery will be connected to the grid through DCAC inverter and enter the power generation mode, and the grid power can be set through APP.
4. Grid charging
When the battery power is low at night and the price of electricity is in the valley, the grid will charge the battery through DCAC bi-directional inverter, and then connect to the grid to generate electricity when the price of electricity is high.
5. Co-charging of PV with the grid
When there is an urgent need to use it as a backup power source, but the battery is low, the battery is charged by the PV panels together with the grid.
6. Use as UPS
In order to guarantee the power supply of critical loads, the system is used as a UPS. When used as a UPS, it can also be set up for grid-connection or charging according to the needs of the scenario.
7. Use as a portable energy storage outdoor power source
When used outdoors, the PV panels can be utilized to charge the battery, while the battery provides AC power to power-using devices through DCAC inversion.
8. Use as a backup power source
In the event of a power outage, the battery provides AC power through DCAC inversion for critical equipment.
9. Parallel mode
Parallel or split-phase can be used when there are the following demands.
①the number of photovoltaic panels is large (can be placed in many locations), can be accessed in groups to realize grid-connected and off-grid applications;
② off-grid use of large power, according to the power needs of parallel power expansion;
③the product can also be split-phase use, greater than or equal to 3 units, can be composed of three-phase system, to meet the use of high-power loads.
④placed in more locations, split-phase convenient placement.
Conclusion
The working mode of solar hybrid inverters is designed to provide a seamless integration of solar energy, battery storage, and grid power, ensuring an efficient and reliable energy supply. By intelligently managing multiple power sources, these inverters help maximize the use of renewable energy, reduce energy costs, and enhance energy independence. As technology advances, solar hybrid inverters will continue to play a crucial role in the future of sustainable energy solutions.
